MAX6509HAUK-T

MAX6509HAUK-T Description

The MAX6509HAUK-T is a programmable, solid-state thermostat from Analog Devices Inc./Maxim Integrated, designed for precision temperature monitoring and control in compact electronic systems. This obsolete but highly capable device operates within a 2.7V to 5.5V supply range, drawing a minimal 32µA current, making it ideal for low-power applications. It features an open-drain, active-low output with a maximum current capability of 20mA, ensuring compatibility with a wide range of logic interfaces. The thermostat offers a ±4.7°C accuracy and supports a programmable switching temperature, allowing customization for specific thermal thresholds. Its selectable hysteresis and trip point functionality enhance system stability by preventing rapid toggling near the setpoint. Packaged in a SOT23-5 form factor and supplied in Tape & Reel (TR), it is optimized for automated surface-mount assembly.
